This experiment was carried out to study the effects of light intensity and soil water regimes on the growth of ginseng seedling. The results were as follows: 1. The maximum light intensity and optimum temperature in 1,le photosynthesis of ginseng seedling were 10,000 lux and 23 $^{\circ}C$. Respiration rate was increased at high temperature. 2. Air and soil temperature under the shading were increased as the increase of light intensity but soil water contents were decreased as the increase of light intensity, whereas air and soil temperature were decreased as the increase of precipitation under the shade b5: soil water contents were increased as the increase of precipitation under the shade. 3. The higher the transmittance of the shade, the greater the specific leaf weight (S.L.W.) and stomatal density. In contrast, however, the contents of total chlorophyll, chlorophyll a and b, and stomatal length was decreased. There was no any significant difference light intensity of the a/b ratio of chlorophyll. 4. The highest photosynthesis was occurred in ginseng leaves grown under the shade 5% L.T.R. and net photosynthesis rates increased with increasing soil water contents. 5. Optimum condition for usable seedling yield were 5% L.T.R. and 3.3% precipitation under the shade. Useless seedling increased with increasing precipitation under the shade.

Test and launch facilities which use oxygen as the propellant of a launch vehicle have hazards of fire and explosion by the leakage of oxygen. Also, the personnel operating the facilities, which use the high-pressured gases like nitrogen and helium in the closed room, is exposed to the hazard of death from suffocation. Consequently, we should keep out of the hazards and the accidents by monitoring the contents of oxygen in the air. The method and the system construction for monitoring oxygen contents in the air and the results from its application to Naro space center are described on this paper.

The sulfuric acid may react with the hardened cement paste and originate expansive products which can induce swelling and disaggregation of concrete. The purpose of this study is to estimate the antibacterial performance of antibiotics and the effect of absorbed condition of restorative mortar, the number of coating times and coating contents with antibiotic on the fundamental properties of restorative mortar spead with antibiotics. Also, testing items such as bonding strength, abrasion contents, contents of water absorption, contents of air permeability was tested to estimate the fundamental properties in this study. In results, the novellus bacillus inhabiting in sewer concrete structures was restrained by antibiotics developed in this study. And bonding strength of restorative mortar spread with antibiotics was similla to that of plain mortar. But, resistance to abrasion, water absorption and air permeability of restorative mortar spread with antibiotics was superior to that of plain mortar.

This study was performed to evaluate the effect of drying methods on the polyphenol contents and antioxidant activities of Hizikia fusiformis. The seaweed was dried using four different conditions: vacuum drying (VD) at $20^{\circ}C$ and $30^{\circ}C$ and hot-air drying (HD) at $40^{\circ}C$ and $60^{\circ}C$. After drying, the total phenol content, DPPH and nitrite scavenging activities of the water extracts were determined. The total phenol contents were significantly (p<0.05) higher in the vacuum dried samples than the hot-air dried samples. DPPH radical was scavenged 82.67% and 83.45% by VD-20 and VD-30, and 70.44% and 71.23% by HD-40 and HD-60, respectively. At pH 1.2, Hizikia fusiformis scavenged 87.43%, 88.45%, 72.14% and 73.45% of nitrite by the treatment VD-20, VD-30, HD-40 and HD-60, respectively. Interestingly, the nitrite scavenging activity was much more reduced at pH 3.0 than at pH 1.2. Through these experiments, we were able to show that the drying conditions affect the total phenol contents and antioxidant capacities of Hizikia fusiformis.

Combustion experiments are carried out to obtain the fundamental data for application of a internally circulating fluidized bed combustor to the combustion of paper sludge wastes. Experimental parameters are identified as secondary air ratio, sludge weight and water contents. The secondary air ratio was varied from 0 to 20% and water content was 14%, 25%, 35%, 45%, 62% and sludge weight was 30g, 60g, 90g. As a result, carbon conversion ratio was higher than injection of primary air. Emission of CO and NOx reduced with an increase of secondary air injection.

A natural air in-bin grain dryer with a grain circulator was developed for on farm use. Natural air drying test for rough rice was carried out to evaluate drying rate, uniformity of moisture content distribution in grain bed and energy consumption. It took 10 days to dry 8 ton of paddy rice from 21.9%(w.b) to 16.7%(w.b) moisture contents using the prototype dryer. The average drying rate was 0.52%/day. The uniformity of moisture content after drying was superior to the conventional natural air dryer where is grains were not circulated during drying periods. The dryer performance evaluation index was 738.3KJ/(kg.water), which was more effective than that of grain circulation t)pe hot air dryer(3,500-5,000 KJ/kg.water).

The purpose of this study was to investigate the influence of air traffic controller's leadership characteristics and hazardous attitudes on the team effectiveness. The effectiveness make use of team efficacy and team commitment. Leadership characteristics and hazardous attitudes make use of the contents of a CRM manual. The study showed following results. 1) Leadership characteristics has a positive influence on the team effectiveness. 2) Hazardous attitudes has a partially bad influence on the team effectiveness. This study was conducted under the auspice of civil and military ATC facilies and by participation of devoting ATC controller's.

The present paper deals with the degradation of nucleotides in the muscle of sea mussel, Mytilus edulis, during drying. Three kinds of samples, raw, hot-air dried, and steamed-and-hot air dried were prepared and the contents of nucleotides were determined by ion exchange chromatography on columns of Dowex 1, X8. ATP and ADP were dominant in the raw muscle showed about $8{\mu}moles/g$, dry basis, respectively. The rate of degadation of ATP was very slow during drying compared with those of fish. The accumulation of ADP and AMP were observed during drying and the amount of total nucleotides (ATP+ADP+AMP) were not decreased remarkably by drying process. IMP was not detected in the all of the samples examined, however, the contents of inosine and hypoxanthine were increased during drying. In case of inosine contents, the hot-air dried sample marked an exceedingly high value equivalent to 8 times of the raw sample whereas steamed-and-hot air dried sample showed 2 times of raw samples.
